Vitamin K‐dependent gamma‐carboxyglutamic acid protein 1 promotes pancreatic ductal adenocarcinoma progression through stabilizing oncoprotein KRAS and tyrosine kinase receptor EGFR

PRRG1 is identified as the transmembrane Gla protein mediating PDAC malignancy. PRRG1 recruits and induces self-ubiquitination of membrane-anchoring E3 ligase NEDD4. PRRG1 exerts a protective role toward KRAS and EGFR by inhibiting NEDD4. The anticoagulant warfarin can be utilized to inhibit PRRG1 and PDAC advancement.
